I have some terminology related questions. 1. What are "lcores": My system has 2 sockets and 6 cores per socket. Are these internal cores --> lcores? So then my system will have 12 lcores? 2. I am trying to work on the Link status change application. I am confused with the terminology, having not much experience, So here is the confusion. I have the compiled application: link_status. ./link_status -c f -n 4-- -q 8 -p 0x0f Here I am setting the portmask as 0x0F as I am going to use 4 ports. Next -q NQ: A number of queues (=ports) per lcore (default is 1) So I donot get the ( number of queues = ports ) statement here. Network cards have RX and TX queues, I have a card which has 7 RX and TX queues. Also my NIC has 4 ports. So each port will have 7 RX and TX queues. So how is this statement (number of queues = ports) per lcore (default is 1) valid. What should be the argument in my case. Please explain. Thanks GNA
